Power - Physics 101 / AP Physics 1 Review with Dianna Cowern

The video explores the concept of power, defined as energy per time, using various examples such as solar power plants, light bulbs, and human bodies. It explains the difference between energy and power, and how power is measured in watts. The video also covers practical applications like hydroelectric power at Niagara Falls and provides a problem-solving example involving force and velocity. Additionally, it touches on the efficiency of energy use in different scenarios and concludes with interesting facts about plasma.

Discuss the concept of potential energy change when climbing hills as explained in the lesson.

How does the power output of Niagara Falls compare to other power sources mentioned?

What is the formula for calculating power in terms of force and velocity?

What conclusion can be drawn about the spring constant when a spring is cut in half?
